Reference member for inspection master in optical three-dimensional measuring machine



FIG. 1 is a perspective view of a reference member for inspection master in optical three-dimensional measuring machine showing my new design;

FIG. 2 is a front elevational view thereof, the rear elevational view being identical to the front elevational view;

FIG. 3 is a right side elevational view thereof, the left side elevational view being identical to the right side elevational view;

FIG. 4 is a top plan view thereof; and

FIG. 5 is a bottom plan view thereof.

FIG. 6 is a cross-sectional view thereof taken on plane 6—6 in FIG. 4;

FIG. 7 is a perspective view showing multiple reference members in an optical three-dimensional measuring machine; and,

FIG. 8 is a perspective view showing multiple reference members on an inspection master.

The optical three-dimensional measuring machine in FIG. 7 and the multiple reference members and inspection master in FIG. 8 are shown in broken lines for illustrative purposes only and forms no part of the claimed design.

The claimed design is used as a component of an inspection master for checking accuracy and calibrating measurement error in an optical three-dimensional measuring machine, and includes a surface to be measured that reflects a measurement beam emitted by the three-dimensional measuring machine. 

The ornamental design for reference member for inspection master in optical three-dimensional measuring machine, as shown and described.
